It might be detecting your phone’s Bluetooth if you have your phone with you when attempting to open the door.
I too was disappointed that I couldn’t get it to stay locked in the dead zone, but I’ve replicated this multiple times:
- Left key in dead zone, walked away, came back and it opened (had phone in my pocket).
- Key in dead zone, walked away, left my phone on the ground a decent distance away, came back, tried the door and it stayed locked.
What year model is your X?
Seems there is no longer a "dead spot" on 2019 or newer.
